Installation Manual
TS4-A with TAP and CCA

IMPORTANT SAFETY INSTRUCTIONS
2
• This manual contains important instructions for installation and maintenance of the Tigo
product models TS4-A-O, TS4-A-S, TS4-A-M, Tigo Access Point (TAP), Cloud Connect
Advanced (CCA), and related Tigo software and mobile applications.
• Risk of electric shock, do not remove cover, disassemble, or repair, no user serviceable
parts inside. Refer servicing to qualied service personnel.
• Before installing or using the Tigo System, please read all instructions and warning
markings on the Tigo products, appropriate sections of your inverter manual,
photovoltaic (PV) module installation manual, and other available safety guides.
• Failure to adhere to these instructions may result in injury or death, damage to the
system, or voiding the factory warranty.
• To reduce risk of re and shock hazard, install this device with strict adherence to
National Electric Code (NEC) ANSI/NFPA 70 and/or local electrical codes. When the
photovoltaic array is exposed to light, it supplies a DC voltage to the Tigo TS4 units. The
TS4 units start in the “ON” state and their output voltage may be as high as the PV
module open circuit voltage (VOC) when connected to the module. The installer should
use the same caution when handling electrical cables from a PV module with or without
the TS4 units attached.
• Installation must be performed by trained professionals only. Tigo does not assume
liability for loss or damage resulting from improper handling, installation, or misuse of
products.
• Remove all metallic jewelry prior to installing the Tigo TS4 units to reduce the risk of
contacting live circuitry. Do not attempt to install in inclement weather.
• Do not operate the Tigo TS4 units if they have been physically damaged. Check existing
cables and connectors, ensuring they are in good condition and appropriate in rating.
Do not operate Tigo TS4 units with damaged or substandard wiring or connectors. Tigo
TS4 units must be mounted on the high end of the PV module backsheet or racking
system, and in any case above ground.
• Do not connect or disconnect under load. Turning off the Inverter and/or the Tigo
products may not reduce this risk. Internal capacitors within the inverter can remain
charged for several minutes after disconnecting all power sources. Verify capacitors
have discharged by measuring voltage across inverter terminals prior to disconnecting
wiring if service is required. Wait 30 seconds after rapid shutdown activation before
disconnecting DC cables or turning off DC disconnect.
• Always assume TS4 units are in “ON” state, or may turn on when restarting.
• The CCA must be on the same AC branch circuit as the inverter to meet rapid shutdown
requirements.
LETHAL VOLTAGE MAY BE PRESENT IN ANY PV INSTALLATION

• Note: The following TS4 products are shipped in the ON position:
• TS4-M, TS4-S, TS4-O
• TS4-A-M, TS4-A-S, TS4-A-O
• Upon exposure of the PV module to sunlight high voltage is
present. Handle with the appropriate precautionary measures.
• Optimization feature does not require CCA & TAP for operation.
• To enable Monitoring and Safety features:
• Collect the TS4 removable barcode label, install and commission
with CCA & TAP.
With add-on units, failing to follow the sequence of installation steps

TS4-A INSTALLATION
Standard modules can be equipped with TS4-A add-on units as
shown below.
Always connect modules to TS4-A inputs before connecting outputs.
Each TS4-A must have a PV module connected to its inputs before
connecting the outputs of TS4-A units in series.
To disconnect TS4-A from a module, disconnect the TS4-A outputs
from the string before disconnecting the TS4-A inputs from the

TAP attaches to module frame using built-in bracket. Mounting holes are also
available in case of frameless modules.
Place TAP within 10m of any TS4 unit in the array, with a maximum distance
of 10m between TS4 units and 35m from TAP to farthest TS4.
Connect multiple TAP units in series and leave terminating resistor in final TAP
only.
Use 4-conductor RS485 (18-22 AWG) cable between TAP and CCA.

Auto PV-Off Error
• A blinking red and yellow LED
indicates that the system
automatically entered PV-Off mode.

Discovery process failed or that the
CCA is not able to connect to the
Tigo server. In case of errors,
connect to the CCA using the
mobile app for more details.
User PV-Off Warning
• A blinking green and yellow LED
indicates that PV-Off mode was
activated manually.
• A solid yellow LED indicates that:
Discovery has not been run,
Discovery completed but did not
nd all expected TAPs or TS4 units, or
CCA is not able to upload data.
Connect to the CCA using the Tigo
SMART app for more details.
SMART App Activity System OK
• A blinking green LED indicates that
the mobile app is connected to the
CCA and is actively in use.
• A solid green LED indicates that
Discovery is complete and found all
expected TAPs and TS4 units, and
CCA is able to connect to the Tigo
server.
Discovery Power Off / No Status
• A blinking yellow LED indicates that
the CCA is scanning for TAPs and TS4
units (part of the commissioning
process).
• An unlit LED indicates that the CCA
is powered off.
